Diagnostics
LCD Off
Make sure that the card is powered: using a digital multimeter, check for the pre-
sence of supply voltage.
In case of no voltage, check the wiring.
If the voltage is sufficient ( Range 195 – 253 Vac ), check the fuse
(3.15AL@230VAC). The fuse is on the card. To reach it, see fig. 20 and fig. 48.
LCD On
In case of operating problems or trouble, the display flashes and the fault identification code appears
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore operation it is sufficient to press
the reset button (detail 6 - fig. 1) for 1 second or use the RESET on the remote timer control (optional) if installed; if the
boiler does not restart, it is necessary to, firstly, eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter "F") which are automatically reset as soon as the value
returns within the boiler's normal working range.

Cure
Check the regular gas flow to the boiler and that
the air has been eliminated from the pipes
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits;
replace the electrode if necessary.
Check the gas valve and replace it if necessary
Check the gas supply pressure
Check the trap and clean it if necessary
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals.
Check the ionization electrode wiring
Check the condition of the electrode
Electrode to earth
Cable to earth
Check the trap and clean it if necessary
Check the card
Check the 5-pin connector wiring
Check the fan
Check the position of the ionization electrode and
replace it if necessary
Check the burner
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Check the trap and clean it if necessary
